Answer:
the answer is A
Step-by-step explanation:
-17 - (-7) = -24
a = -24
Answer:
b) a = -10
Step-by-step explanation:
a + (-7) = -17
simplify
a - 7 = -17
add 7 to both sides of the equation
a - 7 + 7 = -17 + 7
a = -17 + 7
a = -10

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Anita is making bracelets. She has 12 feet of string.
Assume that the length of each bracelet be [x] ft. Then, the total number [y] of bracelets she can make will be -
y = 12/x
Therefore, the total number [y] of bracelets she can make will be -
y = 12/x.

Answer:
the damaged items expected in the case when the 23,025 capacitors produced is 75
Step-by-step explanation:
The computation of the damaged items expected in the case when the 23,025 capacitors produced is shown below:
= (5 × 23,025 capacitors) ÷ (1,535 capacitors)
= 75
Hence, the damaged items expected in the case when the 23,025 capacitors produced is 75
Which of the following shows the solution and graph to the inequality
2x + 1 ≤ 15?
Answer:
C or D
Step-by-step explanation:
I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.
Option D shows the solid dot along with [tex]x\leq 7[/tex] so our answer is
Option D.
The given inequality is 2x + 1 [tex]\leq[/tex] 15.
We have to see which of the given option shows the solution and graph to this inequality.
What are a solid dot and an open dot?A solid dot indicated on a number line graph shows that the given number is also a possible solution, whereas an open dot indicates that the given number cannot be a solution.
We see that in the given inequality, 2x + 1 must be less than or equal to 15.
And the maximum value we can take is 7 because,
2(7) + 1
14 + 1
15
So we can take 7 and any values less than 7 i.e [tex]x\leq 7[/tex] to satisfy the inequality 2x + 1 [tex]\leq[/tex] 15.
We see that Option D gives us [tex]x\leq 7[/tex] along with the solid dot.
Hence Option D is our answer.

A total of 937 people attended the play.
Admission was $2.00 for adults and $0.75
for students. The total ticket sales
amounted to $1,109. How many students
and adults attended the school play?
First complete the equations below, where A
stands for Adults and S stands for Students.
2A + 0.75S = 1,109; A + S = 937
Now use the equations to find the number of
students and adults.
Students = [?]; Adults = []
Answer:
612 students and 325 adults
Step-by-step explanation:
I'll use substitution for this set of equations. I'll start with 2a + 0.75s = 1,109.
2a + 0.75s = 1,109
Subtract 0.75s from both sides.
2a = -0.75s + 1109
Divide both sides by 2.
a = 1/2(-3/4s + 1109)
Make 1/2(-3/4s + 1109) into a single fraction
a = -3/8s + 1109/2
Substitute -3/8s + 1109/2 for a in the other equation (a + s = 937).
-3/8s + 1109/2 + s = 937
Add -3/8s to s.
5/8s + 1109/2 = 937
Subtract 1109/2 from both sides.
5/8s = 765/2
Multiply both sides by 8/5, the reciprocal of 5/8.
s = 612
Now head back to the original equation, and substitute s for 612.
a = -3/8 * 612 + 1109/2
Multiply -3/8 by 612.
a = (-459 + 1109)/2
Add 1109 to -459 and divide by 2.
a = 650/2
a = 325
The system is solved. There are 612 students and 325 adults.

Answer:
divide the cost by the amount.
4.95/5 = 0.99
8.50/10 = 0.85 (better buy)
3.59/3 = 1.20
4.99/5 = 1.00 (better buy)
1.25/16 = 0.078125
1.55/20 = 0.0775 (this one is the better buy however when you round to 2dp they are both the same price of 0.08.)
The same number goes into each box to make two ratios below
4/_ ‘ _/36
Which number goes into both boxes?
A) 6
B)9
C)12
D)18
Answer:
C) 12
Step-by-step explanation:
What you are trying to find is when 4/_ = _/36. The only number that will set these two ratios equal is 12. This is because 4/12 simplifies to 1/3, and 12/36 simplifies 1/3, meaning the two ratios are equivalent.
